import java.applet.Applet;
import java.awt.Graphics;
public class HelloWorld extends Applet{
public uoid paint(Graphics g){
g.drawString("HelloWorld!",50,25);
}
}
然后 编译时输入javac HelloWorld.java出现javac HelloWorld.java
HelloWorld.java:5:cannot find symbol
symbol:class void
location :class HelloWorld
public void paint<Graphics g>{
1 error
声明我已经设置好了各种环境了，是不是要下jre |
